A satellite dish is being designed so that it can pick up radio waves coming from space. The satellite dish will be in the shape of a parabola and will be positioned above the ground such that its focus is 30 ft above the ground. Using the ground as the x-axis, where should the base of the satellite be positioned? Which equation best describes the equation of the satellite?

What are the factors of the expression: 64x2 - 255 ?
(8x - 15)(8x - 15)
(8x - 25)(8x + 25)
(8x - 15)(8x + 15)
(4x + 15)(4x - 15)
Answer:
[tex]\displaystyle Unfactourable[/tex]
Explanation:
This expression is unfactourable with rational numbers. Perhaps you made an errour in your expression. Now, what I think you meant was the expression and factours below:
[tex]\displaystyle 64x^2 - 225 \\ \\ [8x - 15][8x + 15][/tex]
If this was what you meant, then here you are.
Though, I am joyous to assist you at any time.

Two right triangles are graphed on a coordinate plane. One triangle has a vertical side of 2 and a horizontal side of 6. The other triangle has a vertical side of 10 and a horizontal side of 30.
Could the hypotenuses of these two triangles lie along the same line?
No, because they are not similar triangles
No, because one is larger than the other
Yes, because they are both right triangles
Yes, because they are similar triangles
Answer:
D) Yes, because they are similar triangles

Answer:
w^40
Step-by-step explanation:
When you're dividing exponents with the same base you subtract them
This means that w^15/w^5 = w^10
So we have (w^10)^4
When raising an exponent to another exponenent we multiply them
obviously 10*4 = 40 which gives us our answer: w^40
if you have any questions lmk
Answer: w^40
Step-by-step explanation:
w^15/w^5 = w^10
So we have (w^10)^4 and When raising exponents to another exponenent we multiply them
10*4 = 40 which gives us our answer:
w^40

Which statement best explains if the graph correctly represents the proportional relationship y = 3.5x? (4 points)
A graph of a coordinate plane is shown. Points are graphed at 1 comma 3.5 and 2 commas 7. The points are joined by a line.
a
No, the points shown on the line would not be part of y = 3.5x
b
No, proportions cannot be represented on a graph
c
Yes, the points shown on the line would be part of y = 3.5x
d
Yes, all proportions can be shown on the graph of this line
Write an inequality equation equivalent to 3x – 4y = 8?
Answer:
3x-4y=8
-4y=8-3x (subtracting 3x from each side of the equation)
-4y/-4=(8-3x)/-4 (dividing each side of the equation by -4)
y=-2+3/4x
y=3/4x-2

A submarine dives to a depth of 54.6 meters below the surface of water in 4 minutes. What rational number represents constant rate the submarine travels per minute?
Please help me thank u <3 :)
Answer:
13.65 meters per minute
Step-by-step explanation:
Speed is distance traveled over time.
Distance = 54.6 meters
Time = 4 minutes
54.6/4 = 13.65

A city has 15 radio stations, including 3 college radio stations.
What is the probability that a randomly chosen radio station in this city is a college radio station?
Write your answer as a fraction or whole number.
Answer:
1/5
Step-by-step explanation:
There are 3 college radio stations out of 15 this means that 3/15 of them are college radio stations. 3/15 simplifies to 1/5
if there are 400 billion birds in the world and 5 billion die each year and 395 million are left but 10 billion birds are made each year how many birds are there really
You already said the answer. There are 400 billion birds in the world. ("if there are 400 billion birds in the world...")
Also, if you wanted an approximate calculation of everything, you would have to tell us how many years there are. Is this a trick question?

The equation below describes a proportional relationship between x and y. What is the constant of proportionality?
Y= 5/6x The constant of proportionality is?
Which expression represents that x was doubled and then decreased by 25% ?
Answer:
x1.5
Step-by-step explanation:
say x is 1 then is we multiply by 2 we get 2 and if we decrease 2 by 25% we get 1.5 and that number works for any number instead of multiplying by 2 and decreaseing by 25% as they reveal the same number.

Observe the two scenarios involving electrically charged objects. Predict what will happen when you bring the objects close together.
Two scenarios with electrically-charged objects.
A. The balloon will attract the soda can, while the two balloons will repel each other.
B. The balloon will attract the soda can, while the two balloons will do nothing.
C. The balloon will repel the soda can, while the two balloons will also repel each other.
D. The balloon and soda can will do nothing, while the two balloons will repel each other.
Answer:
i think it is D or B
Step-by-step explanation: hope this helps and have a great day :)
Answer:
From what I know, C.
Step-by-step explanation:
I have done this experiment years ago, and what happened was the balloon made the can roll away, which is called repelling, and the two charged balloons actually started "floating" away from each other and required force to keep them together, which would also be classified as repelling or repulsent.

Step-by-step explanation:
a number cube is labeled 1 to 6 .richard will roll the number cube 500 times and record the results.ABout how many times could richard expect to roll and even number
Answer- 250 times
Step-by-step explanation: This is because a number die is random and if it were based on even and odd, the chances would be 50/50
Richard could roll cube 500 times, then he gets 250 times an even number.
What is the probability?The Probability in mathematics is the possibility of an event in time. In simple words, how many times that incident is happening in any given time interval.
Given:
A number cube is labeled 1 to 6.
Richard will roll the number cube 500 times and record the results.
2, 4, and 6 are even numbers in the cube.
The probability
= Number of favorable outcomes/ total number of outcomes
= 3/6
=1/2
That means,
if Richard could roll cube 500 times, then he gets even number 500/2 =250 times.
Therefore, Richard will get 250 times an even number.

It costs David $0.52 per day to have this newspaper delivered to his home. The equation below can be used to find the cost (C), in dollars, to have the newspaper delivered for w weeks.
C=(0.52) (5) (w) What will it cost David to have this newspaper delivered to his home for 19 weeks?
Answer:
$69.16
Step-by-step explanation:
There are 7 days in a week.
so you multiply 0.52 x 7= 3.64
Then 3.64 x 19= 69.16
Therefore David will have to pay $69.16 to have this newspaper delivered to his home for 19 weeks.
